Polyshield® Foundation / Baseplate Systems

The Polyshield® polymer concrete baseplate and foundation system is the superior solution for cost-effective, high-performance pump installations. This single, complete unit replaces the traditional baseplate and concrete foundation for pump-driver sets.

STRUCTURAL TECHNOLOGIES’ Polyshield® is the preferred pump foundation solution that takes advantage of the unique properties of polymer concrete. As a chemical-resistant foundation system that is easily put into place, then filled with standard concrete, the Polyshield® system can be completely installed and operable in less than two days.

Once installed, your Polyshield® system will provide excellent corrosion resistance over the long term, as well as vibration damping and resistance to twisting and diaphragming.

ANSI Polyshield® Systems

STRUCTURAL TECHNOLOGIES’ ANSI Polyshield® is a one-piece polymer concrete foundation and baseplate shell and a removable polymer concrete motor block. Pumps and motors are bolted to the polymer surface with cast-in alloy inserts. Each polymer and motor block accomadates two NEMA (IEC) frame sizes. Within limits, motor blocks may be changed to future frame sizes. Polymer motor blocks are supplied in different heights and insert locations for all ANSI group sizes and motor combinations. Eight pre-engineered foundation sizes for all ANSI and ISO frame designs with NEMA or IEC motors.

Custom Polyshield® Systems

STRUCTURAL TECHNOLOGIES’ Custom Polyshield® is a polymer concrete foundation and baseplate shell with large and thick alloy mounting surfaces for affixing both the pump and motor. The unit is designed to accommodate large end suction, split case, double suction and axial flow pumps with NEMA and non-NEMA motor frames. Custom Polyshields allow large pumps and motors to be installed quickly and reduce installation cost compared to fabricated metal baseplates!

Polyshield® Improves Equipment Reliability

Life cycle costs for pumps and other equipment decrease significantly due to improved unit performance resulting from:

High vibration damping characteristics

Longer seal, bearing, and coupling lif

Longer Mean Time Between Planned Maintenance (MTBPM)

Low maintenance requirements

No paint peeling

No baseplate or foundation deterioration

Polyshield® Reduces Total Installed Cost

Polyshield’s pre manufactured shell and simple in place completion of the construction drastically reduces the downtime for repair and replacement and the total installed cost compared to conventional fabricated concrete foundations and steel base plates. Along with up-front savings the Polyshield® system’s corrosion resistance and proven track record provides longer life. Finally its inherent design and material composition provides greater stability and dampening capabilities that translate into not just a more durable foundation proven but longer life for the equipment it supports
